2系统配置
2.1创建oracle用户和组
2.1.1创建用户和组
[root@centos-y ~]# groupaddoinstall #创建用户组oinstall
[root@centos-y ~]# groupadd dba #创建用户组dba
[root@centos-y ~]# useradd -goinstall -G dba -m oracle #创建oracle用户，并加入到oinstall和dba用户组(-g主组-G副组)
一般还应该创建oper用户组，并将oracle用户添加进来（如下操作），这里省去。
groupadd dba
useradd -g oinstall -G dba,oper -m oracle
2.1.2查询用户组是否授权成功
[root@centos-y ~]# groupsoracle
oracle : oinstall dba
[root@centos-y ~]# id oracle
uid=1003(oracle) gid=1003(oinstall)groups=1003(oinstall),1004(dba)
2.1.3设置用户oracle的登陆密码
不设置密码，在CentOS的图形界面没法登陆
[root@centos-y ~]# passwdoracle
Changing password for useroracle.
New password:
BAD PASSWORD: The password isshorter than 8 characters
Retype new password:
passwd: all authenticationtokens updated successfully.
查看新建的oracle用户
[root@centos-y ~]# id oracle
uid=1003(oracle) gid=1004(dba)groups=1004(dba)
2.2创建@R_301_457@安装目录
2.2.1创建安装目录
在根目录创建oracle@R_301_457@安装目录，为后续安装做准备
[root@centos-y ~]# cd / #进入根目录
[root@centos-y /]# mkdir -p/u01/app/oracle #oracle@R_301_457@安装目录
[root@centos-y /]# mkdir -p/u01/app/oraInventory #oracle@R_301_457@配置文件目录
[root@centos-y /]# mkdir -p/u01/app/database #oracle@R_301_457@软件包解压目录
2.2.2设置目录权限
[root@centos-y /]# chown -Roracle:oinstall /u01/
[root@centos-y /]# ll /u01/ #查看权限
total 0
drwxr-xr-x. 5 oracle oinstall53 Oct 17 16:51 app
2.2.3上传安装文件并解压
可通过WinSCP等工具将@R_301_457@安装文件上传到Linux系统。
将安装文件夹解压到之前创建的目录。
unziplinux.x64_11gR2_database_1of2.zip -d /u01/app/database/ #解压文件1
unzip linux.x64_11gR2_database_2of2.zip-d /u01/app/database/ #解压文件2
2.3修改OS系统标识
oracle默认不支持CentOS系统安装，修改文件/etc/RedHat-release 内容为RedHat-7
[root@centos-y /]# vi/etc/redhat-release
entOS Linux release 7.2.1511(Core)
查看修改结果
[root@centos-y /]# cat /etc/redhat-release
redhat-7
2.4安装依赖包
CentOS7安装oracle@R_301_457@需要以下依赖包：

2.5防火墙和SELINUX设置
2.5.1查看防火墙状态
[root@centos-y ~]# systemctlstatus firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded(/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)

2.5.2临时关闭防火墙
这样只能暂时关闭防火墙，重启后失效。
[root@centos-y ~]# systemctlstop firewalld.service
查看防火墙状态。
[root@centos-y ~]# systemctlstatus firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon

2.5.3禁止使用防火墙
永久关闭防火墙，重启后仍然生效。
[root@centos-y ~]# systemctldisable firewalld.service
Removed symlink/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink/etc/systemd/system/basic.target.wants/firewalld.service.
2.5.4关闭selinux
修改“/etc/selinux/config“，将SELINUX的值“enforcing“修改为”disabled“。需重启才能生效。
[root@centos-y ~]# vi/etc/selinux/config
# This file controls the stateof SELinux on the system.
# SELINUX= can take one ofthese three values:
# enforcing - SELinux security policy isenforced.
# permissive - SELinux prints warningsinstead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one ofthree two values:
# targeted - Targeted processes areprotected,
# minimum - Modification of targeted policy.Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
2.6修改内核参数
打开“/etc/sysctl.conf“，在文本最后添加配置参数
[root@localhost~]# vi /etc/sysctl.conf
net.ipv4.icmp_echo_ignore_broadcasts= 1
net.ipv4.conf.all.rp_filter = 1
fs.file-max = 6815744 #设置最大打开文件数
fs.aio-max-nr = 1048576
kernel.shmall = 2097152 #共享内存的总量，8G内存设置：2097152*4k/1024/1024
kernel.shmmax = 2147483648 #最大共享内存的段大小
kernel.shmmni = 4096 #整个系统共享内存段的最大数
kernel.sem = 250 32000 100 128 #信号量有关的参数
net.ipv4.ip_local_port_range =9000 65500 #可使用的IPv4端口范围
net.core.rmem_default = 262144
net.core.rmem_max= 4194304
net.core.wmem_default= 262144
net.core.wmem_max= 1048576
保存退出，执行“sysctl-p“加载系统参数使配置生效
[root@localhost~]# sysctl -p
net.ipv4.icmp_echo_ignore_broadcasts= 1
net.ipv4.conf.all.rp_filter = 1
sysctl: setting key"fs.file-max": Invalid argument
fs.file-max = 6815744
fs.aio-max-nr = 1048576
sysctl: setting key"kernel.shmall": Invalid argument
kernel.shmall = 2097152
sysctl: setting key"kernel.shmmax": Invalid argument
kernel.shmmax = 2147483648
sysctl: setting key"kernel.shmmni": Invalid argument
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
sysctl: setting key"net.ipv4.ip_local_port_range": Invalid argument
net.ipv4.ip_local_port_range =9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
提示 sysctl: settingkey "……": Invalid argument，这里可以忽略，不影响后续安装。
2.7进程会话配置
在文件“/etc/security/limits.conf “中添加以下内容
[root@centos-y /]# vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
说明：“/etc/security/limits.conf ”是 Linux 资源使用配置文件，用来限制用户对系统资源的使用
2.8配置oracle用户环境变量
在文件“/home/oracle/.bash_profile”添加以下内容
[root@centos-y ~]# vi /home/oracle/.bash_profile
export ORACLE_BASE=/u01/app/oracle#oracle@R_301_457@安装目录
exportORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1#oracle@R_301_457@路径
export ORACLE_SID=orcl #oracle启动@R_301_457@实例名
export ORACLE_TERM=xterm #xterm窗口模式安装
exportPATH=$PATH:HOME/bin:$ORACLE_HOME/bin #添加系统环境变量
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib #添加系统环境变量
export LANG=C #防止安装过程出现乱码
exportNLS_LANG=AMERICAN_AMERICA.ZHS16GBK #设置Oracle客户端字符集，必须与Oracle安装时设置的字符集保持一致
注意，上述添加的内容中：ORACLE_SID=orcl ，orcl要与待创建的oracle实例名称一致。
配置完成，保存退出（：wq!）。运行以下命令，使配置生效
[root@centos-y ~]# source/home/oracle/.bash_profile
vim /etc/profile
if [ $USER = "oracle"]; then
if [ $SHELL = "/bin/ksh" ];then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
关于“/etc/profile”可参考以下文章：
《Linux/etc/profile文件详解》：http://www.linuxidc.com/Linux/2010-08/27742.htm
2.9其他配置
vim /etc/pam.d/login
session required/lib/security/pam_limits.so
session requiredpam_limits.so
IP和主机名：
[root@localhost db_1]# vi/etc/hosts
# Do not remove the followingline,or varIoUs programs
# that require networkfunctionality will fail.
127.0.0.1 localhost.localdomainlocalhost
192.168.1. 99 CentOS-y
3安装配置
3.1安装@R_301_457@软件
3.1.1设置图形界面
查看root用户下是否已设置DISPLAY变量
[oracle@centos-y database]$echo $DISPLAY
如果有值（比如“:0.0”）出现，则说明已设置DISPLAY变量；否则，执行以下命令
[oracle@centos-y database]$export DISPLAY=:0.0
测试图形界面是否能正常显示
[oracle@centos-y database]$xclock
显示时钟，则正常
3.1.2安装过程
[oracle@centos-y database]$ cd/u01/app/database/
2) 执行安装指令
尝试执行“./runInstaller “命令安装，但安装过程中出现图形界面显示异常，弹出窗口缩成一块，无法放大。故改为以下命令安装：
“./runInstaller -jreLoc/usr/lib/jvm/jre-1.8.0“
[oracle@centos-y database]$./runInstaller -jreLoc /usr/lib/jvm/jre-1.8.0

4问题记录
这里对安装过程中出现的一些问题做一些总结，以备后用。
问题1
设置图形界面，提示无法打开显示器：“Can't open display “
解决方案：
[oracle@centos-y database]$xclock
Error: Can't open display:
查看
[oracle@centos-y database]$echo $DISPLAY
不显示信息，则执行以下命令
[oracle@centos-y database]$export DISPLAY=:0.0
再次查看
[oracle@centos-y database]$echo $DISPLAY
:0.0
＃＃（这句话可以写进.bashrc，就可以省去每次设计的麻烦）
参考： http://www.jb51.cc/article/p-cnxqhaoa-bgg.html
问题2
安装检查先决条件，报物理内存不足：
解决方案：
查看当前虚拟内存

问题3
安装oracle11g@R_301_457@过程报错：PRVF-0002Could not retrieve local nodename
解决方案：
该错误主要是由于hosts文件配置问题：
vi /etc/hosts
修改hosts文件中添加服务器ip以及hostname即可.
192.168.1. 99 CentOS-y
问题4
安装到%86时报错：Error in invoking target 'agent nmhs' of makefile
解决方案:
保留安装界面，另外开启一个终端窗口，将ins_emagent.mk文件中的 (MK_EMAGENT_NMECTL)更改为$(MK_EMAGENT_NMECTL) -lnnz11，然后在安装过程中点击Retry即可。
[oracle@centos-y ~]$ cd$ORACLE_HOME/sysman/lib
[oracle@centos-y lib]$ viins_emagent.mk
定位到：(MK_EMAGENT_NMECTL)，添加 lnnz11
回到安装界面，点击“Retry“，即可正常安装
